Ah, the Tasmanian tiger, a fascinating creature indeed. They were carnivores, so they mostly ate small to medium-sized animals like wallabies and birds. Just like a painter carefully chooses their colors, the Tasmanian tiger carefully selected its meals in the wild.
no
If the two species occupies the same continent, which they do not, then a tiger could very easily eat a Tasmanian devil. Currently, there are no opportunities for tigers to consume Tasmanian devils.
whatever they find
The Tasmanian wolf was not a wolf, but a marsupial. Its proper name was Thylacine, although it was most commonly known as the Tasmanian tiger. It is not known whether the Thylacine was a solitary hunter, or whether it hunted in packs. It was known to eat mammals, as it was a dasyurid, or carnivorous marsupial.
food
The Tasmanian tiger, or thylacine, primarily fed on small to medium-sized animals and was estimated to consume about 2 to 4 kilograms (4 to 9 pounds) of food daily. Their diet included kangaroos, wallabies, and other small mammals, and they were known to hunt in the early morning or late evening. The exact amount varied based on availability of prey and individual needs.
No animal is truly vicious, although some are more likely to be aggressive than others. The Tasmanian tiger was hunted to extinction because they were blamed for hunting livestock. However, there is not enough knowledge of their hunting strategies to determine whether they killed prey in a quick or a slow manner.
The correct name for the Tasmanian wolf is Thylacine. This creature, also known as the Tasmanian tiger, is extinct. When it was still in existence, it was a hunter and predator; its purpose was not to be useful to mankind.
The Tasmanian devil's only native competitor for food is the quol. However, the quoll is a much smaller dasyurid, and is certainly not a competitor for the carrion which Tasmanian devils eat. Foxes have been introduced fairly recently into Tasmania, and they, too, are competition for the Tasmanian devil.
The Tasmanian wolf or Tasmanian tiger, also known as the thylacine, is an extinct marsupial carnivore. The thylacine was exclusively carnivorous. For more information on the diet of the thylacine, click on this link.
How much can the Amur tiger eat?
No. Although both carnivorous mammals, this is where the similarity between Tasmanian devils and dingoes stops. Tasmanian devils are marsupials, with a pouch in which they rear their young. Dingoes are relative "newcomers" to Australia, and placental mammals.
